On June 4, 2025, version 6.15.24 has been released. This version allows the user to excavate nets that do not contain all activities that are present in the provided event log. To control what percentage of the activities are covered by the excavated net, a new “Coverage” slider is introduced in the configuration panel for the plugin.
As an example, we run the Xcavation plugin on the “pdc2024_11011100.xes” event log from the PDC 2024 data set with the following configuration:
Note that, like the Fitness weight, the Coverage weight is set to 100, which means that it is considered very important. As a result, the plugin will attempt to cover all activities, if possible. With this configuration, the excavated net looks like follows:
The result is a Petri net that contains all activities from the event log, but that is very spaghetti-like. In contrast, we could move the Coverage slider down to 20, making the coverage less important:
Although the latter excavated net does not contain all activities (t16 and t25 are not covered), the latter excavated net is likely to provide more insights. For this reason, selecting a lower Coverage weight may make sense.
